Towers of Kublai Khan

Computer version of a puzzle invented in Asia in deep antiquity, and which came to Europe only in the 19th century - the Tower of Hanoi. There are three platforms and a certain number of rings, minimum three, but more often much more. All these figures are of different sizes and initially on the leftmost platform, on top of each other, at the bottom is the largest, at the top is the smallest. The player is asked to move all rings in the same sequence on the rightmost platform, in a minimum amount of moves. Of course the difficulty is that you are never allowed to put a larger ring on top of a smaller ring.
